There are some features worth mentioning when modelling power grids as multilayer networks: At least one inter-edge connecting upper layer for a component No pair of planar nodes share the same name. That is, there is no replica of planar nodes, the setting of which is quite different from prototypical multilayer networks.

Inter-edges exist between adjacent layers and direct towards lower layers. There is geographical information associated with intra-edges, but not with inter-edges. All the inter-edges represent transformers. Terminals of any inter-edges are unique. Put another way, there is no pair of inter-edges sharing a terminal.

Interface for Power System Analysis Electric devices can be modelled using built-in classes or customised classes, then instance using supported Python packages for power system analysis can be returned. Current, supported tools are: pandapower : combines the data analysis library pandas and the power flow solver PYPOWER to create an easy to use network calculation program aimed at automation of analysis and optimization in power systems.

PyPSA : a free software toolbox for simulating and optimising modern power systems that include features such as conventional generators with unit commitment, variable wind and solar generation, storage units, coupling to other energy sectors, and mixed alternating and direct current networks. Power flow for unbalanced three-phase-four-wire power grids. In terms of: Power flow for unbalanced power grids with laterals cables with less than three phases.

OpenDSS is an open-source distribution system simulator. Generally speaking, a bus impedance matrix is to be built for the whole power grid, then used to calculated power flow for given snapshot s. Documentation website. I have stored my nodes in a dictionary Vector3, Node. On a floor, all the nodes are on the same Y so, the elevation is included but ignored. I guess, i have to check Granberg's heuristic calculation.

Edit:If you can't figure out an admissible heuristic you can always fall back to Dijkstra's algorithm. Another edit: Scratch that. As long as you don't have any weird teleporting going on, straight line distance will always be an admissible heuristic. Last edited: Oct 19, Kiwasi , Oct 19, Ok i'll go check that.
